APPARATUS FOR REGULATING THE SUPPLY OF LlQUlDS FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 377,293, dated January 31, 1888.

Application filed February 19, 1887. Serial No. 228, 171.

(N model.) Patented in England December 7, 1877, No. 4,643, and

March 13, 1886, No. 3,575.

To all whom it may concern.-

Be it known that I, WILLIAM DAVIES, a subject of the Queen of Great Britain, and residing in the city of Liverpool, in the county of Lancaster, England, have invented new and useful Improvements in Flushing Apparatus for later-Closets, (for which I have obtained patents in Great Britain, No. 4,643, of the 7th of December, 1877, and No. 3,575, of

IO the 13th of March, 1886,) of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which Figure 1 represents a vertical section of the apparatus embodying my invention. Fig. 2

is a plan of the apparatus.

My invention relates to means for discharging from a cistern, tank, or reservoir a definite quantity of water for flushing the hopper of a water-closet; and it consists in the peculiar means, hereinafter described and claimed, operating on the old principle of the siphon.

A is a tubular or capshaped piston, which moves up and down in a chamber, B, sur- 2 rounding an outlet or stand pipe, D, the top of which stand-pipe is higher than the level of the liquid to be emptied from the reservoir E. The cap portion of the piston A may have sides parallel or tapered, or partly parallel and partly tapered, and the piston may or may not be constructed with a packingring, as shown at F.

The communication between the chamber B and the reservoir is through a passage or open- 5 ing, G, in the side of the chamber, at same point of which passage or opening a movable diaphragm or valve, H, is placed, opening toward the chamber B and closing toward the reservoir E.

The apparatus may be worked by a lever jointed to the top of the piston, and provided with a balance-weight on the opposite side of the fulcrum, as shown, to which lever proper connection by the usual pull chain or rod may 5 be made. I do not, however, confine myself to any specific means for operating the piston.

The action of the apparatus is as follows: The piston A being at the top end of the chamher 13, the weight of the water in the reservoirE opens the valve H and permits the liquid to fill the chamber B and part of the hol- 10W piston A, displacing the air in the chamher and the piston to the level of the water in the reservoir. The piston is then pressed down in any convenient manner, whereby the valve or diaphragm H is closed, and the air remaining in the piston is forced down the stand-pipe or outlet D, and is followed by the water in the piston and chamber until a siphon action is set up, which will by suction open the valve or diaphragm H, and thereby allow the whole of the water in the reservoir to escape down to the level of the top of the opening or passage G.

I am aware that it is not new to apply a siphon to a water-closet tank or reservoir, and to start it into action by lifting the water-level to the bend or descending point of the siphon by means of a piston, and i do not claim this broadly. My invention is, however, distinctive in novelty in that the tubular piston A itself forms the short leg of the siphon; also in the application of the valve H and in the forcible expulsion of the water down the long leg of the siphon, which makes my apparatus much more positive and sensitive.

It is obvious that my invention is not limited to use for water-closets alone; but it may be equally well applied to the emptying of any cistern or reservoir.

Having thus described my invention, what I claim as new is The combination of the reservoir and chamber B, having valve H between, the stand-pipe D, extending up through said chamber, and the hollow piston A, titted within chamber B and surrounding the stand-pipe and adapted, as described, to act both as a plunger and the short leg of the siphon.
